English was the official language of the Space Corps, but the Jupiter Mining Corporation also made extensive use of Esperanto. Many of the corridors of Red Dwarf are labelled in both English and Esperanto.

Bazookoids were common tools used by the JMC to blast apart rocks and ores. Holo-saws were also sometimes used.

The JMC had a number of different divisions; for example, the "JMC lift division" can be seen on some of the Red Dwarfelevators, and "JMC food products" can be seen on many of the Red Dwarfvending machines.

Before construction of Red Dwarf was complete the JMC made cut-backs removing the bio-neural computer networking, the Quark-level matter/anti-matter Engine Core and causing the ship to be laid out differently, including removing a Karaoke Bar on C deck. ("Back in the Red I")

Notes

Behind the scenes

The Jupiter Mining Corporation was a mining company that had an office at room 02-842 on the Promenade of Starbase Deep Space 9 in Star Trek: Deep Space Nine This establishment, which seems to be named after or originate from Jupiter, is listed on a Promenade directory map seen in many episodes of DS9. It is a deliberate reference to Red Dwarf.
